I saw in all guides for destroyers and markmans twin shot and random shot are really bad because they break the mobility. I tested twin shot, and it's don't change the animation or the mobility, it just pierce and that's very very useful for PVE. "normal x attack makes you stuck in place and vulnerable to attack." but i get stuck in place without this skill activated. Why?
And another question, can random and twin shot be active on the same time?
